Specification of Letters Patent.

Patented Aug. 27, I907.

Application filed December 18, 1903. Serial No. 185,696.

To all whom it may concern:

Be it known that I, THOMAS GARNEY, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new-and useful Improvements in Cash-Registers, of.

which I declare the following to be a full, exact description.

This invention relates to improvements in cash registers and has moreparticular relation to improvements in registers of the so-calledtwo-motion type in which certain kcysor setting elements are firstoperated and a handle or leversubsequently moved to complete theoperation of the machine.

One of the several objects of the invention isto provide a cash registerwith an improved printing mechanism.

Another object is to provide improved time printing devices.

The invention consists of certain novel constructions, combinations andarrangements of parts, all of which will be hereinafter moreparticularly set forth and claimed.

In the accompanying drawings forming part of this specification: Figure1 represents a vertical transverse section through a machine of theclass mentioned, with my improvements applied thereto. Fig. 2 alsorepresents a section through the same, taken to the left of the bank ofclerks keys. Fig. 3 represents an end elevation of the machine, showingthe printing mechanism. Fig. 4 represents a vertical section through themachine illustrating the operation of the machine in conncction with theclock winding mechanism. Fig. 5 represents a detail front elevation ofthe clock mechanism and connections with the dial removed. Fig. 6represents a top plan view of the pheck carrier or table. Fig. 7represents a detail side elevation of the printer Fig. 8 representsadetail side elevation of the platen operating devices. Fig. 9represents a detail side elevation of one of the special keys andcotiperating parts; and Fig. 10 represents a detail front elevation ofthe printing wheels.

As a number of the parts shown in the present invenclear, and

tion are similar to the machine patented to me Tune 23,

1896, No. 562,707, I will refer to said patent for such detaildescription of the parts as is not hereinafter given.

The operation of the key levers, keys, indicators and connections formnopart of the present invention but are included in a co-pendingapplication Serial No. 185,697 filed December 18, 1903. It will be necssary, however, in order to secure an understanding of the devicescovered by the present invention to describe a number of the parts ofthe machine which are intimately connected with the constructionscovered by the present application. Described in general terms, however,the machine may, be said to comprise a series of pivoted key levers 1mounted upon a transverse shaft 2 ind-arranged to become coupled attheir rear ends to a key coupler 3 so that when said coupler is actuatedby an independently movable means, the key levers will move with saidcoupler and thus actuate the parts connected to said levers. Each of thekey levers is pro vided with an operating standard 4, these standardshaving hook projections which engage and actuate rocking frames 5carrying counter operating segments. As shown in the aforesaid patent,the rear ends of the key levers support indicator standards so that whensaid lovers are operated by the movement of the key coupler, theindicators, which are of tablet formation, will be raised into exposedpositions and so latched. In the present machine, however, I havereplaced these indicator standards or 'stems by a number of verticallymovable standards similar thereto but having no tablet plates at theirripper ends. These indicator standards 9 control the movements of therotary indicators as will be hereinafter more particularly described.

The keys and key lerers.Reverting now to the key levers 1, I willdescribe how these levers are constructed so thatthey may be given aninitial movement to bring them into coupling relation with the keycoupler 3. Located across the front of the machine are a number of keys10 arranged in two transverse rows. The keys proper in the presentillustration have suitably marked heads and'pcndcnt shanks. When one ofthe keys proper isdcprcsscd the lower end of it shank, which is normallyresting upon the upper forward edge of one of the key levers, rocks saidkey lever upon its pivot against the tension of a spring 23 whichconnects the key lever to a pivot cd pawl 24 mounted thereon andnormally engaging the flange 3* of the key coupler to force the keylcvcr downward into its normal position.

When any one of the keys 10 is depressed it depresses the forward end ofits respective key lt'\'(1 l and thereby clcvates the rear end of thislcvcr. As the rear end of the lever moves upward the pawl 24 is rockeddownward against the tension of its spring 23, and the upper hooked end27 of the key lever is moved to a position above the coupling flange 3of the key coupler. When the key coupler is now operated its flange 3will engage undcr the hook projections 27 of all of the operatedkcylcvcrs and thus simultaneously actuate all of said levers. When thekey coupler is finally returned to its normal position the key leversare given an additional downward movement by the pawls 24, which therebyreturn said key lovers to their normal positions. Whenever any one ofthe key lovers 1 is given its initial movement by the depression of itsrespective key, it is held in its depressed position by one of a seriesof rock detcnt plates 28. These plates are loosely journaled upon atransverse shaft 29 and are formed upon their lower edges with a seriesof notches througlrwhich the respective key levers pass. Each of the keylevers is provided with a locking projection 30, and the detents 28 arenormally held against these projections by coil springs 31 which connectsaid detents to a slotted guiding plate 32, mounted on the main frame.

well as a special detent for each of the special keys hereinafte rdescribed.

When a key lever. is depressed in a manner before described, itsprojection 30 will force its detent 28 slightly forward until theprojection has passed free of the detent, when the latter will resumeits normal position overthe key projection and lock the key lever in itsdepressed position. While all of the key detents 28 are independentlymovable upon the shaft 29, they are arranged to be simultaneouslyactuated by the shaft to release all of the key levers. For this purposethe shaft is provided with a plurality of radial arms 33, one for eachof the detents, and so positioned that when the shaft 29 is rocked allof the detents will also be rocked. The rocking of the shaft 29 isautomatically accomplished (by means not shown herein) upon eachoperation of the machine to permit all of the key levers to return totheir normal positions.

.As before stated, the key levers are first moved int coupling positionin relation to the key coupler 3 and the latter then operated tocomplete the movements of the key levers. This operation of the keycoupler is accomplished by an arm 42 fast to one end thereof,

shown in Fig. 1. This arm 42 is connected to a lever 35, similar to thelever 35, but located at the opposite end of the machine. The connectionis established by a link 43 provided with two spaced apertured lugs 44.The lower lug 44 forms a guide for sliding a sleeve 45 fast to a bar 46pivoted to the outer end of the arm 42.

Said bar 46passes-through the upper lug 44 thereby forming a guide forthe same. A coil spring 47 is interposed between the upper lug 44 and aflange 48 formed on the sleeye 45.

By'the of the lever 35 will be communicated to the key coupler, butshould the lever 35 be violently operated the mounted radially in guideplates 61 and 62 secured to operations as the spring 47, which isinterposed between banks of keys.

key coupler 3 will not immediately follow these violent the parts, willabsorb the shock. In order that the levers 3-5 and 35 may be moreconveniently operated the same are connected across the front of themachine by a hand bar 50 which extends directly in front of the Thelevers 35 and 35 are pivoted upon the key shaft 2 and each of the sameis provided with a pendent arm 51, which is connected-by a coil spring52 to the main frame. By this means, after the bar 50 has been depressedit is automatically returned to its normal position when released. In,the above description I have set forth the construction and operation ofthe several banks of amount keys and their connections. At the left-handside of the machine, however, is located what might be termed anindepe'. .dent-bank of keys representing the different departments orclerks, as desired. These keys are the main frame and are provided withpins 63 which contact with coil springs 64 mounted about the shanks ofthe keys and between the pins 63 and the plate 62. These pins effectthe'return of the keys to their normal v There is one "if the detents 28for each of the banks of keys as ove described connections the movementspositions when they are otherwise unrestrained. Each of the pins 63 alsoprojects into one of a series ofdiagonal slots 65 fol med in a slidingsegmental plate 66, mounted between the plates 6]. and 62.

It results from the above construction that when any one of the keys 60is depressed the plate 6(iis forced upward' and rearward and remains soas long as the key remains in its lower position. When the plate (36 isforced upward in this manner it is latched in its upper position by aspring actuated pawl 67 loosely mounted upon the shaft 29, as shown inFig. 2, and formed at its end with a locking notch 68 which, when theplate (56 is elevated, receives a pin 69 mounted on said. plate.

jecting pin 70' which is arranged to be engaged by a pin '71 mounted onthe rock shaft 29, upon which the pawl' 67 is journaled.

It will be seen from the above that when the shaft 29 is rocked asbefore stated, the pawl 67 will be moved rearward and its notch 68disengaged from the pin 69, which action will permit the plate 66 toresume its normal position. i

By reference to Fig. -.2 it will be seen that there are six of the keys60, representing six different clerks or departments. [is the operationof the different keys in this bank must result in or control themovements of certain'parts to graduated degrees, I providcthe extendedtrunnion 83 of the key coupler with an upwardly projecting lever 84,best shown in Fig. 2. This lever is provided at its upper end with a pin85 which projects into an angular cam slot 86 formed in the lever 87,which is journaled upon a short transverse shaft 88 mounted in the mainframe. The lever 87 is provided near its forward end with a pivotedsegmental arm 89 having an inclined edge 90 and a curved edge 91. Whenthe arm 84 is actuated by the movement of the key coupler the lever 87will be correspondingly moved by-the pin 85 traveling down in theoperative portion of the slot 86. When the lever 87 is so rocked thepivoted arm 89 is moved forward until its inclined edge 90 contacts withthe lower end of the stem of the depressed key. The continued movementof the lever 87 causes the arm 89 to be carnmed downward and backwarduntil the lower end of the key stem rides over the curved surface 9].When the arm 89 is canuncd downward, as above described, a lug 92mounted thereon is forced into one of a series of recesses 93, formed inthe periphery of a plate 94 which is fast on the shaft 88. The plate 94is thus picked up sooner or later and thus given a greater or lessmovement by said lever. The lug 92 is drawn out of the recesses 93 by acoil spring 100 one end of which is fastened to a lug 101 formed on thearm 89 and the other end to a pin on the lever 87.

In the above description I have set forth in detail the construction andoperation of the different banks of keys and their cooperating devicesand I will now (le- ,scribe the connections and operation in conjunctiontherewith of the several indicators.

'The indicat0rs.-'As before stated, the plate 94 of the special key bankis moved different positions according to the operated value of the key60 depressed. I therefore utilize this movement to set a suitablespecial. in; dicator by interposing any suitable mechanism between theplate 94 and said indicator. As these connections,

however, form no part of, the present invention 1 have not shown thesame in the drawings.

As before stated, each of the key lovers of the amount banks isarranged, when operated, to elevate a standard or rod 9. Each of theserods is provided with alatching projection 125 and a lifting projection126. A rocking plate or yoke 127 is pivotally mounted at the earof themachine. This rocking plate or back rod is operated to release orsupport'the standards in-a manner well known in the art and needing nofurther description here.

As before stated, each of the rods 9 is provided at its upper end with alifting projection 126. When one of the rods?) is elevated itsprojection 126 will engage one of a series of steps 132 formed upon arocking frame 133, which is journaled upon the shaft 110, as bestshowrrin' Fig. 1. As the different steps 132 are located at differentdistances above the lifting projections 126 of their respective keys, itwill be seen that the operation of the different rods 9 will operate theframes 133 correspondingly. Each of these frames 133 is provided with alaterally projecting lug 134 through which projects an arm 13 5formed ona lever 136 whichis journaled upon the shaft 110, and is provided at itsupper end with a segmental rack 137 meshing with a pinion 138 of itsrespective rotary indicator 139. A coil spring 140 surrounds the arm 135and bears with its opposite ends against said arm and the'lug 134. Apin141 mounted in the arm 135 below the lug134 prevents said arm frompassing out of the aperture in the lug and thus holds the parts in theirnormal set positions: Should one of the rods 9 be raised over rapidlyand thus engage the frame 133 with considerable force, the spring 140will yield and thus prevent any shock to the indicator The subsequentexpansion of the spring, however, will cause the indioator'to-take upthe proper set position even after the movements of the frame 133 haveceased. Such a violent impact. of the lifting projection 126 with theframe 133 would also cause the frame to be thrown upward a distance inexcess of the movement imparted toit by the lifting standards or rods.The frame, however, -is eventually returned to a position in which itbygthe flange 130 of the back rod 127.

engages the lifting projection. of its rod 9 by a coil spring142 whichconnects 'said frame 133 to the main frame. The levers 136 rest againstatransverse rod 143 when .in their normal positions.

I It will be seen frorn the above that after one of the rods 9 iselevatedit'is latched in its elevated position When latched in thisposition its projection 126 will support its respective frame 133 in'aposition equivalent to the value of the operated key, and the indicator139 will thus display the, proper amount at the indicator openings inthe cabinet of the machine. 7

- As shown in said 'copending application a number of special keys,representing Charge, f Paid out, Received on account 'and No sale arelocated at different points along the regular amount key-board. Theoperationsfo'f these keys and key levers are substantially the same asthe amount keys and key levers excepting, as before stated, that each ofthese special key levers is provided with an individual detentwherevating standards 4 as they are not connected with the concentricportions 185.

counter actuating devices but each of the same is provided with one ofthe operating standards 9. These standards 9 of the special keys areconnected to a suit able indicator by any known and desirable devices.

Printing devices-Each of the amount key levers is formed with a slothaving a cam portion 157 and a concentric portion 158. Mountedtransversely of the machine are a series of nested sleeves 159 supportedby a shaft 160. Each of the sleeves 159 as well as the shaft 160 isprovided with two upwardly projecting arms 161.

Each pair of these arms is connected to a transverse bar 162 whichprojects under the lower ends of the cam slots 157 of the key levers ofthe bank to which the particular bar 162 pertains. When the key lever isdepressed at its forward end the walls of its particular cam slot willengage its respective bar 162 and thereby rock the arms 161 and theshaft or sleeve connected thereto to a greater or less extent. After thearms 161 are rocked to their full extent the continued movement of thekey levers will cause the barsl62 to pass into the concentric slots158,. whereby the bars will be locked into the positions'to which theyhave been set during the period of the free movement of said key levers.

By reference to Fig. 2 it will be seen that the outer end of the shaft160 and also the outer ends of the sleeves 159 are provided with arms163 formed with segmental racks 164. These racks mesh with pinions165'mountcd upon the inner ends of a series of nested sleeves 166 and asupporting shaft 167. These sleeves and shaft are provided at theirouter ends with a series of type car- I,

is provided with a pin 173 which projects into a notch 174 formed in apivoted lever 175 to which the rear end of the spring 172 is connected.The rear end of the lever 175 is provided with an anti-frictiou roller176 which engages a cam 17.7 mounted upon the rotation shaft 74. Theformation of the cam 177 is such that the lever 175 is operated at theproper period to bring the pawls 170 into locking and alining engagementwith the star wheels.

The above description covers the connections between the amount keylevers and their printing type wheels. Located beside the main printingtype wheels is a type wheel for printing special char-act ers representing the special keys. This type wheel is actuated through the medium ofa segmental rack 1S0 mounted on an arm 181 which is fast to a transverserock shaft 182, as best shown in Fig. 2] This shaft, as best shown inFig. 9,

is provided with a series of upwardly projecting plates 183 formed withslots having cam portions 184, and Anti-friction rollers 186 are mountedon the respective special key levers and operatein the cam slotssubstantially in the same manner &

mental rack 103, before described. All of the printing wheels areprovided with double sets of types arranged upon diametrically oppositesides whereby duplicate impressions may be taken for both the detailstrip and the check Loosely journaled upon the 'shaft 167 to the left ofthe amount printing wheels are'three timeprinting wheels 187, 188, and189. The wheel 189 is provided with duplicate sets of type numeralsextending from 1 to 12. The wheel 188 is provided with duplicate typenumbers representing thedifferent multiples of 5 and extending from 5 to55. The type wheel 187 is provided with two series of letter types whichare alternately A and P as representing ante-meridian and post-meridian.The three wheels 187, 188,- and 189 are'actuated by a three-pronged pawl190 which.

cooperates with ratchet wheels 191 secured to the said type wheels.The'pawl 190 is of a variety having a plurality of different lengthedtines which cooperate with deep tooth ratchet notches in the wheels 191to provide for transferring movements to move one wheel after thepreceding wheel has moved a half revolution, which operation. is old andwell known iii-the art. The pawl 190, as best shown in Fig; 3, ispivoted into the upper end of the arm 192 fast to the sleeve 193 whichis journaled upon a short shaft 194, secured to the main frame. Thesleeve 193 also carries an arm 195, providedwith a pin. 196. This pinprojects into an elongated slot 197 formed in the lower end of an arm198 which is fast to a short shaft 199, journaled on the main frame, asclearly shown in Fig. 3. The shaft 199 carries a rearwardly extendingarm 200 which is formed at its rear end with an elongated slot 201. Thisslot receives a pin 202 mounted on the lower end of a rod 203. The rod203, as best shown in Fig. 5, is formed with a slot or aperture 204 atits upper end for the reception of the end of a lever 205, which isjournaled upon the main frame. The lever 205 is connected by a link 206to apivoted bell'crank 207. This bell crank carries an actuating pawl208 which engages aratchet .wheel 209, fast to the arbor of theminute-hand so that 4 to prevent retrograde movementof the same." The tothe frame of the clock work. vided with an extension 210 having afslot217 formed clock mechanisrrf may be of any suitable construction,

and uponthe minute arbor of the same I mount an operating ratchet 213.This ratchet cooperates with the ,upper beveled end of a bell cranklever 214 which is journale'd upon the main frame, and is held in itsnormal position, by a coil spring 215 which connects it The lever 214 isproof thesa'me will actuate the lever 214 every five minutes. 3 if .Itwill be seen from the above that when the lever 205 is actuated theminute-hand is moved through a distance equal to five minutes and theminute printing wheel is moved one notch. Mounted upon, the Windingarbor 219 is a winding ratchet 220. This ratchet is engaged by aspring-pressed pawl 221 mounted upon a short'lever 222 which is pivotedupon the main frame and is connected by a link 223 to a bell crank lever224. This lever, as best shown in Figs. 4 and 5, is pivotally connectedto a vertically movable ,rod 225. This rod is provided at its lower end.wi tha laterally projecting pin 226 which extends into an elongatedslot 227 formed in an arm 228. This arm is fast upon a transverse shaft229 which is suit; ably journaled in the main frame. This shaft carriesa vertically extendingarm 230, said arm together with the shaft, tendingto rock forward under the im;

pulse of a coil spring 231 which surrounds the shaft,

and is connected at one end to the arm 230 and at its end of the lever234. When the cash drawer 237 is released 'theaction of the spring 231tends to force the arms 230 and 234 forward and partly eject the drawerfrom the cabinet or casing. The forward movement 'of the levers or arms230 and 234 are limited by thepin 232 which strikes against the under-"side of a stationary bracket 239 mounted on the main frame. when theshaft 229 rocks forward upon th opening of the cash drawer the pawl 221is retracted loo through the connections before described so that when ithe cash drawer is again closed and-"the pawl moved forward it willengage and actuate the ratchet wheel 220 and thus wind up the clockspring. When the longer wind the clock spring as the closing movement ofthe drawer willsimply causethe lever 234 to move: A

rearward withoutanymovementbeing imparted to the 1ever230. As most ofthe devices in connection with this time printing mechanism are shownand claimed in my co-pending application No. 64,558, I will not enterinto'any further description here. u

The devices for securing the impressions from the respective type wheelscomprise two platens 240 and 241, (see Fig. 3). The platen 240 ismounted upon the platen lever 242 which is fast to a shaft 243 passingthrough the main frame, while theplaten 241 is journaled upon a similarlever 244. The platen levers of devices illustrated in Figs. 2.and Thesedevices comprise a plate 248 fast to theiiiiri'erend of said shaft andprovided with two spaced" anti-friction rollers 249 and 250. Therotation shaft 74 is provided with .the platen against the tension ofits spring. Just prior to the time when the pawl passes free of theroller 250 the cam 251 engages the roller 249. Upon the backwardmovement of the key coupler and the attendant rotation of the shaft 74the cam 251 is advauced far enough to release the platen lever and tailstrip 255. This strip passes between the platen 240 and the type wheelsand under two guiding bars 256 and 257 The strip is led froma supplyroller 258 and is fed forward by a feeding roller 259 This latter rolleris provided with a winding ratchet 260 fast thereto. The ratchet 260 isengaged by a retaining pawl 261 and an operating pawl 262, said pawlsbeing connected by a coil spring 263. The pawl 262 is pivotally mountedupon a bell-crank lever 264. A pin 265 mounted on one end of thisbell-crank projectsthrough the frame of the machine and is connected bya link 266 to a crank arm 267 fast to the extended journaled end 83 ofthe key coupler. By this means the bell crank lever 264 is oscillatedupon each operationof the machine and feeds the detail strip forward asuitable distance. The pin 265 also supports a pendent hooked bar 268,the lower end of which is normally held into engagementwith a ratchetwheel 269 by a coil spring 270 which connects the upper end of thehooked bar to the bell crank lever. The ratchet 269 is secured to oneend of an absorbent inking and feeding roller 270 journaled upon themain frame. The inking ribbon passes about this roller and also aboutsuitable guiding studs 271 mounted upon the main frame. The ribbon alsopasses about an anti-friction roller 272 mounted upon a lever 273 whichis journaled upon the main frame and is normally forced forward by acoil spring 274, which surrounds its journal and bears with oneend-against said lever and the other against the main frame. The ribbonis thus normally held taut and under tension. When it is desired tochange the ribbon or re-ink the absorbent roller the levcr 273 is movedrearward and is retained in this rearward position by a hooked pawl 275,which is hooked over the guide bar 256. A series of spring-pressedretaining pawls 276 are mounted upon the main frame and are arrangedtoengage the ratchet wheels 191 of the time printing types to preventretrograde movement of the same. The lower platen lever 244 for securingan impression upon the check is arranged to be coupled to the upperlever 242 by a sliding plate 277 slotted to receive a journal pin 278 ofthe lower platen lever and a pin 279 secured to the upper portion of theplaten'lever.

The upper slot of the plate 277 is arranged to receive a pin 280 mountedupon the upper platen lever when the plate is raised in the manner to benow described.

The lower portion of the plate 277 is formed with a horizontal slot 281into which projects a pin 282 mountcd upon a pivoted lever 283. Thislever 283 is pro vided with a pin 284 which projects into an elongatednotch 285 formed in the rear arm of a bell crank lever 286. The upperarm of this bell crank lever is pivoted to a check holder or slide 287,which slide is normally retracted in the position shown in Fig. 3 by acoil spring 288 which connects it to the main frame. The rear end of theslide is formed with a slotted arm 289 which receives a guiding pin 290,fast to the main frame. The forward end of the slide is provided with aspring clip 291 for securing the check upon the slide. The rear portionof the check holder is suitably aperturcd to permit of the passage ofthe platen 241 thercthrough, whereby the check is forced against thetypes. After the check has been inserted in the holder 287 the holder isforced rearward. This movement of the check holder rocks the levels 286and ,283 and elevates the slide 277 to couple the two platen leverstogether. When the slide 277 is so elevated the pin 282 passes'above thelower end of a hooked lever 293 and thus permits said lever to be drawnrearward under the pin by a coil spring 294 which connects the lever tothe main frame. This lever, as best shown in Fig. 2, engages the camfast on the shaft 74 as shown in dotted lines in Fig. 7' and is therebyoperated at the proper time to permit all of the check holding devicesto return to their normal posi tions and leave the lower'platcn leverinoperative. A rigid arm 287 projects up through the aperture former. inthe carrier 287 to support the check in pro er position before the checkprinting platcnis elevated to of- 1 fect the impression.

It will be seen from the above that the operation of inserting the checkand pushing the check holder rearward couples the lower platen to theupper platen so that the check will be printed and that thc parts there-10 5 after automatically return to their normal positions in j which thecheck platen lever is inoperative. By this means the check printingdevices remain inactive unless a check is desired.

The rotation shaft 74, before mentioned, receives a complete rotationupon each operation of the machine through the medium of the key coupler3. To accomplish this result the key coupler is provided at itsrighthand end with a laterally projecting pin 290 which ex'- tends intoa horizontal slot 291, formed in a vertically movable rack plate292.This plate is guided at its lower end by a pin 293 mounted upon the mainframe and projecting into an elongated slot 294 formed in said plate, Acoil spring 295 connects the plate to the main frame in such manner thatthe tension of the spring is 12 alternately exerted above and below thepin 293 which acts as a fulcrum upon which the plate 292 rocks. Theupper portion of the plate 292 is formed with two vertical arms 297formed upon their inner edges with rack teeth. The shaft 74 is providedwith a pinion 298 which is arranged to be alternately engaged by therack teeth on the arms 297 as the plate 292 is rocked upon its fulcrum.The plate 292 is held to vertical movement in its different adjustedpositions by a lug 299 which cooperates with a stationary flange 300 ofthe main frame.

. mechanism, of a printing device including time printing The aboveconstruction is old and well known in the art and no further descriptionof the same is thought to I 186,697 executed on even date herewith.
